This allows multiple guardians to submit the signatures in parallel without causing costs with all transactions because conflicting txs won't be mined.
* bridge: add secp check instruction
* solana: update to secp solana upstream
* solana: iteration on secp
* solana: fix secp instruction
serialization indices were off and secp ix data was serialized twice
* solana: optimize ix serialization
* agent: send multiple chunks of signatures
* doc: update protocol spec
* solana: store signatures in siginfo; reconstruct signed VAA in webinterface
* solana: reformat
* solana: add rustfmt config
- Build buf and protoc-gen-go and use it to build Go proto packages
- Rename agent proto package to agent.v1 (to prevent namespace collisions and conform to buf's standards)
- Default to DOCKER_BUILDKIT=1 for CI setup
- Add incremental Docker build for solana/agent
- Move build machinery to top level
